HEATER.

SPECIFICATION forming part of Letters Patent No. 502,335, dated August1, 1893.

Application filed December 10, 1890. Serial No. 374,176- (No model.)

.To all whom it may concern.-

Be it known that 1, JOHN A. WEAVER, a citizen of the United States,residing at Pequea, in the county of Lancaster and State ofPennsylvania,haveinvented certain Improvements in Heaters, of which thefollowing is a specification.

This invention relates to improvements in that class of heaters whichare used to supply heat to apartments other than that in which theheater is placed; and the invention consists in the peculiarconstruction and combination of parts, as hereinafter fully describedand specifically pointed out in the claim.

In the accompanying drawings, which form a part of thisspecificationFigure 1 is a side elevation of a stove embodying myinvention. Fig. 2 is a transverse section on the line 00-03, Fig. 1.Fig. 3 is an enlarged section of the hot-air chamber on the line y-y,Fig. 1, and Fig. 4., a vertical section of the same on the line zz, Fig.3.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A represents the heater; B,the oven; C, the firechamber, and c, the smoke-pipe.

b is a hot-air flue leading from the oven B to a room above. Ribs d areformed on the inside of the back plate of the oven above and below theopening 1, leading into the flue b, the ribs being slotted or grooved toreceive a sliding-plate, D, adapted to close said opening. This plate isoperated by a rod (1, extending out through a perforation in the side ofthe oven and havingahand-hold, 01 formed on the end. When the openinginto the flue b is closed the plate D occupies the position shown infull lines in Fig. 2, and when open the plate is drawn back into theposition shown by the dotted lines CF. The outward movement of the plateD is limited by contact with the side of the oven, and the inwardmovement by stops formed in the inner ends of the grooves in the ribs d.Above the top of the heater there is an enlargement of the flue b,forming a hot air-chamber H, which is preferably circular in horizontalcross-section, as shown in Fig. 3. Around the periphery of the chamber Hare equidistant openings h,

through which hot air passes from the chamber. Inside of and restingagainst the vertical wall of the chamber there is an annular cut-01f M,resting on an annular rib or shoulder or, located around the lower edgeof the chamber. Through the cut-0E there are openings m, at equaldistances apart, adapted to register with the openings h in the wall ofthe chamber H. Plates 772, between the openings m and connecting theupper and lower parts of the cut-off, are of somewhat greater width thanthe openings h, in the wall of chamber H, and serve, when the cut-0E isproperly adjusted, to close the openings h. The cut-oft is operated by arod or handle, N, attached thereto and projecting outward through aslot, h, in the wall of the chamber. This slot is of such length and solocated that when the handle rests against one end thereof the openingsin the cut-off register with the openings in the wall of the chamber,and when the handle rests against the other end the plates m cover thoseopenings. In the flue b, above the hot-air chamber, there is placed anordinary damper R.

In operating, when it is desired that all the heat should be retained inthe oven 13, for baking, cooking, or other purposes, the opening 1 inthe back thereof is closed by the sliding plate D; but when the heat isto pass into the flue b the plate D is drawn from in front of theopening Z, as shown by dotted lines 01 Fig. 2. If it is intended thatthe hot-air pass to an upper apartment the openings h in the hot-airchamber are closed by the cut-01f M and the damper R is opened; but ifit is desired that the hot-air escape into the room in which the heateris located, the damper R is closed and the cut-off shifted to uncoverthe openings h. When the flue b is not used the opening can be coveredwith an ordinary removable cap, or if the heat is to pass from the oveninto the room, by a similar perforated cap.

Having thus described my'invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination, in a heater, of a fire chamber and an oven located overthe same, a hotair flue opening into the oven, a cut-0E in the 100 ovenadapted to close said flue-opening, an air-chamber formed in the hot airflue and having openings through the sides, a rib or shoulder formedabout the lower edge of the chamber, a cut-off resting on said rib orshoulder and having openings and plates adapted to register alternatelywith the openings in the air-chamber, a handle on the cut-off of theair-chamber passing through a slot in the Wall thereof, and adarnperlocated in said flue 10 above the hot-air chamber, substantially as andfor the purpose specified.
